Description

Technical Field

[0001] This invention relates to the field of computer technology, and in particular to a multifunctional chassis base. Background Technology

[0002] Computers are essential devices for modern work and life. During computer use, a chassis support is often needed to support the chassis. This support is usually a plate-like structure with wheels on the bottom. To ensure the chassis can be positioned correctly, blocks are usually installed on the chassis for positioning.

[0003] For example, application number CN202223211102.7 discloses a computer chassis support, comprising a base, a mounting plate on the top of the base, a stabilizing mechanism fixedly connected to the bottom of the base, a groove on the top of the base, and an adjustment mechanism inside the groove. The adjustment mechanism includes a first threaded rod, the left end of which is movably connected to the left side of the groove via a bearing. This computer chassis support, by setting an adjustment mechanism, can limit the four corners of the chassis through four fixed blocks and limiting blocks, thereby mounting it on the top of the mounting plate. When the chassis height is too low in the usage environment, rotating the first threaded rod with a handle causes the mounting plate and chassis to move upward or downward under the action of the movable block and push rod, thereby adjusting the chassis height to adapt to different usage environments and improving the chassis's adaptability during use.

[0004] However, the existing chassis bottom support blocks require separate operation during use, which is complicated. In addition, since the position of the chassis air vent is fixed, it is easy for the chassis air vent to be directly facing the opposite staff in the office, resulting in a poor user experience.

[0091] The specific usage and function of this embodiment are as follows:

[0092] The oscillating operating component 15 rotates, and the oscillating operating component 15 drives the first oscillating drive shaft 16 to rotate through a worm gear transmission mechanism composed of an oscillating worm 1501 and an oscillating worm wheel 1601.

[0101] The second oscillating bevel gear 1701 is coaxially and fixedly connected to the left end face of the second oscillating drive shaft 17. The second oscillating bevel gear 1701 meshes with the oscillating driven bevel gear 1301 on the same side to form a bevel gear transmission mechanism. In use, rotating the oscillating operating member 15 drives the first oscillating drive shaft 16 to rotate through the worm gear transmission mechanism formed by the oscillating worm 1501 and the oscillating worm wheel 1601. The first oscillating drive shaft 16 rotates through the bevel gear formed by the first oscillating bevel gear 1602 and the oscillating driven bevel gear 1301. The transmission mechanism drives the two sets of positioning seats 13 on the left to rotate. At the same time, the two sets of positioning seats 13 on the left drive the two sets of swinging second transmission shafts 17 to rotate simultaneously through a bevel gear transmission mechanism composed of a swinging second bevel gear 1701 and a swinging driven bevel gear 1301. The swinging second transmission shafts 17 drive the two sets of positioning seats 13 on the right to rotate through a bevel gear transmission mechanism composed of a swinging second bevel gear 1701 and a swinging driven bevel gear 1301. This achieves simultaneous rotation of the four sets of positioning seats 13 and adjusts the installation angle of the four sets of positioning seats 13 to meet the positioning requirements of different size models.

The positioning transmission shaft 6 drives the positioning screw 14 to rotate via a bevel gear transmission mechanism composed of the positioning driving bevel gear 602 and the positioning driven bevel gear 1401. The positioning screw 14 drives the positioning intermediate transmission plate 7 to slide up and down via a screw-nut transmission pair composed of the positioning screw 14 and the positioning intermediate transmission plate 7. The positioning intermediate transmission plate 7 drives the four sets of positioning lifting components 8 to slide up and down simultaneously. The positioning lifting components 8 drive the positioning intermediate transmission shaft 9 to rotate via a gear and rack transmission mechanism composed of the positioning first gear 901 and the positioning first rack 801. The positioning intermediate transmission shaft 9 drives the positioning sliding component 10 to slide via a gear and rack transmission mechanism composed of the positioning second gear 902 and the positioning driven rack 1001. The sliding of the positioning sliding component 10 causes the positioning block 11 to be pressed against the corner of the chassis. The pressing of the four sets of positioning blocks 11 achieves the positioning of the chassis, ensuring that the chassis is located in the center position of the base, thus realizing the positioning of the chassis.
